Image processing apparatus and method

摘要

The invention provides an image processing apparatus and a method therefor capable of registering a paper fingerprint at a position that considers a matching accuracy and security. The image forming apparatus executes: a paper fingerprint acquisition step of reading a paper fingerprint (S1101-S1104); a paper fingerprint registration determination step of determining whether paper fingerprint information acquired in the paper fingerprint information acquisition step is suitable as a paper fingerprint for paper (51105-51107) ; and a paper fingerprint registration step of registering a paper fingerprint detected in the paper fingerprint registration determination step as a paper fingerprint for the paper (s803).
